3 Claims. (01. 68-189) This invention-relates to apparatus for uniiormlydyeing rayon cakes.

The object of the invention relates to the apparatus for dyeing rayoncakes at a predetermined density, to secure uniform dyeing through allparts of the cakes.

. The second object of the invention is the production of apparatus of asize which will enable rayon cakes of predetermined dimensions, to beuniformly compressed to a predetermined density to secure uniformdyeing.

The third object of theinvention relates to the apparatus for dyeing aplurality of rayon cakes and the like, independently of one another atpredetermined densities to secure uniform dyeing when treated with dyeliquor.

The fourth object of the invention relates to and the like of variousdimensions, and producing apparatus which will suit the variousdimensions of rayon cakes oi difierent manufactures.

' The sixth object of the invention relates to bosses 28 and'2'l..Anannular projection til, entends up from the inner iaceoi the wall 25.

A cover 85, is provided for the top open end oi? the wall 2 i and isdetachably bolted to the flange 22, by means oi the bolts 36.

A carrier 40, havingthe cylindrical wall 48, with threaded openings 82,the. top wall 48, and

V the bottom annular end 46, is positioned upon the annular projection30, of the operating tank 2%, and detachably supported thereon.

Supporting spindles 45, at their outer ends have the threaded shanks 46,and at their inner ends are shown with the threaded shanks 48. Anhexagonal spacer portion 49, is indicated adjacent to each of the shanks48. The shanks 6d,

are in threaded engagement with the threaded openings 42, of the wallBi, of the carrier it. Each of the spindles 45, is indicated with theopenings 50, extending through its wall. A cap the apparatus fortreating rayon cakes and the like of various dimensions to produce cakesof uniform densities and changing the nature thereof.

In the drawing Fig. 1 represents a vertical section of an operating tankand its appurtenances, with portions in full lines, for simultaneouslydyeing a plurality of rayon cakes at a predetermlned density; Fig. 2 isan enlarged longitudinal section of a, rayon cake and its appurtenancesfor dyeing the same; Fig. 3 is a view similar to Fig. 2 with portions infull lines, of a pair of rayon cakes and their appurtenances for dyeingthe same and Fig. 4indicates a. section of Fig. 2 on the line 4, l. V

Referring to Figs. 1, 2 and 4, an operating tank 20, is indicated withthe cylindrical wall 2|, having the flange 22, at its upper end andhaving the Bosses 26 and 21, with threaded openings are integral withthe wall 25. Pipes 28 and 29 respectively, have their upper ends inthreaded engagement with the threaded openings in the v bottom wall 25.

55, with the bearing end 56, and the thread 57, on its inner cylindricalface is in threaded engagement'with each threaded shank 4t.

Baskets for the cakes of rayon to be treated are each designated in itsentirety by the numeral 60. Each of said baskets in this instance,comprises the disc shaped supporting wall 6!, with the axial opening Bioand which has integral therewith and at right angles thereto thecylindrical outerwall 52. Perforaztions 63, extend through the wall 62.l

The baskets at their ends opposite the I walls 8| are open. In eachbasket 80, is detachably positioned the adjusterdesignated in itsentirety by the numeral 10. Each adjuster 10, comprises the cylindricalcore H, with the perforations 12. The ends of'the core H, are indicatedat I3 and 14.

An outer disc shaped closing wall 18, extends from and is integral withthe core II, and the outer face of said wall 18, is spaced somewhat fromthe end I3, of the core 1|. i

From the wall 18, extends one end. of the outer tapered adjusting wall80, having the perforations 8|. The wall, joins with the disc shaped endwall 82, at a point somewhat distant from the end ll, of thecore H.

Referring to Fig. 3, the wall of the carrier is again shown at ll, withone of its threaded openings 42.

A supporting spindle is again indicated at 45 with its threaded shank46, at one end and the threaded shank 48 at its other end with thespacer portion 48. The openings for the spindle are again shown at 50.The cap 55, is again indicated with its bearing end 50. In this instancea pair of the baskets 60, for the rayon cakes to be treated aresupported on the spindle 45. Each of the baskets again comprises thesupporting wall Bl, which hasintegral therewith the outer cylindricalwall 62, with the perforations 63.

The walls 80 join with the disc shaped end walls- .82, at a pointsomewhat distant from the ends' It will be noted in this in- 14, of thecores stance, see Fig. 3, that the wall SI, of the outermost basketbears against the end 13, of the core of the adjacent adjuster I0. andthat the bearflows through the cakes Q0, from their outside to theirinside and escapes through the perforations 8|, of, the wall 80, of theadjuster 10. The

liquor then flows through the perforations '12, of the cores I I. Theliquor next flows through the openings 50, and enters the supportingspindles 45, and from the latter it enters thecarrier 40 and is finallyled away through the pipe 28. By

ing end 56, of the cap 55, bears'against the end 13, of the core ll, ofthe outermost adjuster I0.

The rayon cakes treated by the apparatus are each designated in itsentirety by the numeral 90. Each of the rayon cakes is shown with theouter cylindrical face 9|, the bottom flat face 92, the top flat face93, and the inner tapered face 94.

To dye the rayon cakes 90, they are positioned in the baskets 60, asindicated in the drawing.

. The cakes 90 when inserted into the baskets 60,

are somewhat longer than'the latter, and the thickness of the cakes aresuch that they may be easily located in the space betweenthe basket 60and the adjuster l0.

The outer cylindrical face SI, of each cake treated bears against theinner face of the wall 62, of its basket 6!), the bottom flat face 92,bearing against the inner face of the supporting wall 6|.

The adjuster 10, bears with its outer circum-' ferential portionof-theclosing wall 18, upon the 90, and the said cakes are forced inplace with the required predetermined pressure in each of the baskets60, to secure a uniform density through all portions of the cakesoperated upon.

The dye liquor may now be forced through the pipe 28, and enter thesupporting spindles 45. The dye liquor isforced through the openings 50,of the supporting spindles 45, and then flows means of the operationsjust described the dye liquor flows through the rayon cakes from theirouter faces to their inner faces as already referred to.

Various modifications may be made in the invention and the presentexempliiication is to be taken as illustrative and not limitativethereof.

Having described the invention I claim:

' 1. In an apparatus for dyeing rayon cakes the combination of asupporting spindle having perforations, a plurality of baskets havingouter cylindrical walls with perforations coaxial with and supported onthe spindle, each of said baskets being adapted to support a rayon cakehaving an inner tapered longitudinal face, an adjuster in each 'basketand coaxial therewith, a core for each adjuster surrounding thesupporting spindle, each adjuster having an outer tapered wall withperforations adapted to bear against the tapered faceof its coactingrayon cake, each adjuster having a disc shaped wall at one end adaptedto bear against one of therayon cakes and a wall at its other end, meansto longitudinally move each adjuster to simultaneously compress therayon cakes to a desired pressure and density.

2. In an apparatus for dyeing rayon cakes having inner tapered" faces,the combination of a basket having a. cylindrical wall with perforationsfor supportinga rayon cake, a supporting spindle for .the basket havingperforations, co-

axial with and extending through the basket, an adjuster adjustablypositioned in the basket, said adjuster comprising a core havingperforations and surrounding said spindle, said adjuster having an outertapered wall with perforations and having a disc shaped wall at one endextending into the basket with its circumferential edge bearing againstthe inner face of the cylindrical wall of the basket, 2. disc shapedwallat the other end of the adjuster extending into the basket and meanscoacting between the adjuster and the supporting spindle tolongitudinally position the adjuster in operative position, the

' tapered wall of the adjuster bearing against the through theperforations 12, of the core ll,,of I

each adjuster 10. The dye liquor is then forced uniformly through allportions of the cakes 90, with a uniform pressure. The liquor afterpassing through the rayon cakesescapes from the baskets 60, through theperforations 63, of the walls 62, and is dropped into the operating tank20. From the latter the dye liquor escapes through the pipe 29. With theoperations just described the dye liquor flows through the rayon cakesfrom their inner to their outer faces.

A four-way valve and pump, not shown, is connected to the pipes 28 and29.

. If desired, the dye liquor may enter the op- ,walls 62, of the baskets(ill. The liquor then tapered face of the rayon cake in the basket tocompress said cake to a predetermined pressure and density.

. 3.
